Templeton drag pipes

Skat Trak 76 rollout 12 paddle haulers

Custom drilled rotor

QuadTech foam/cover

AM Chassis +6" "T" stem and -8 width +6 forward single arm rigid front end

ASV C5 clutch lever

Turbo Chassis +4 swing arm

Direct Drive CNC 10x2" front wheels W2 (spindle mounts)

Sandtoyz Unlimited 18x3 front tires

Custom aluminum "bumper"

Custom lightweight rear caliper

Fly Racing start button

ECATV tether

Modified lightweight subframe

Big thanks to Quality Powdercoat (qpcoat.com) for the subframe powder coating and swing arm coating, Brett (sand2kinc.com) for helping me out with some tips when putting together... And numerous members from other forums for helping me get the parts to build this.

It weighed in at 312lbs wet with this 25lb axle, a 12lb aluminum JJ&A axle is enroute.

Very nice project Rappy. An expensive one I bet. Are you going to race it?

Thank you!

Yes, it's a total money pit lol, could be spending money on worse things I suppose.

Yep, it's strictly a racing quad now with the rigid front end, no dunes or trails for me!

looks like she will displace a bit of sand at the crack of the throttle :yes:

Maybe a little:wink:... We will see. First debut is on the 18th, I'll post the helmet can footage.

Just to clean it up a little bit, it's not practical at all lol. That's part of building a drag bike, trying to hide wires, and just make it look very simple.

Couldn't get the dumb thing to run half right today. Best was a 5.52, which should be more like a 4.7x.

There is no fuel above 6500rpm. Will have to figure that problem out tomorrow. Here's a quick video-

Last weekend and yesterday, and tomorrow actually. Last weekend, took first place in the mod class, there were probably 10-15 bikes... Unfortunately no timers. Yesterday was T&T at West Michigan Sand Drags. Ran a 5.11 off the trailer with it having little traction and messed up gearing, ran a 5.0 at 57mph, and it was all down hill from there. It just spun like crazy!

Last week-

      Hello all!
      By P_syko
      Hello all! I’m new to the 4 wheeler world, but not new to the mechanic world. I was a diesel mechanic for many years and last year got into jet skis. I just bought a 1987 Yamaha moto 4 350 and now learning the ins and outs of 2 stroke engines. Looking forward to learning all the things.

      Oxidized or faded plastic body parts
      By Randel1
      I recently read an article about restoring or at least improving the looks of faded and discolored plastic body parts. In the article it suggested using a 50/50 mixture of boiled linseed oil and paint thinner. You mix it up and apply it with a brush or rag to rub it in and remove the oxidation. I curious to find out if anyone has had experience with doing this and what was their short/long term results of doing so. I would hate to try it and find out that a few weeks/months down the road my plastic body parts self destruct.

      Polaris ATV Valve Adjustment
      By PolarisRich
      I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
      My bike is a 2005 Sp 500 HO.
      I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
      Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
      [ATTACH]1021[/ATTACH]
      then the side cam cover (5-8mm bolts).
      [ATTACH]1023[/ATTACH]
      Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
      [ATTACH]1022[/ATTACH]
      Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
      The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
      timing marks are parallel to rocker cover gasket surface.
      The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
      Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
      the flywheel into the center of the hole.
      [ATTACH]1023[/ATTACH]
      Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
      [ATTACH]1024[/ATTACH]
      [ATTACH]1025[/ATTACH]
      To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
      The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
      I'd give it a 4 out of 10 on the skill level scale.
      I hope this helps!
      Thanks Rich

      1998 YFM400 Kodiak 400 Bogs at 3/4 throttle
      By Does_This_Look_Bent?
      Hey everyone, I just replaced the carp on my 98 Kodiak 400 with PN#4SH-14101-00-00. It starts and idles perfect, but once it’s good and warmed up, it bogs out at 3/4 throttle or more… it sounds like it’s bouncing off a rev limiter haha… I tried the air fuel screw, all the way in and out 2-1/2, and it made it a touch better… tried 2 turns and no different. Am I missing something?
